ROD AND PIPE CUTTER.

SI'EQIFIGATION forming part of Letters Patent'No. 543,369, dated July23, 1895.

Application filed May 5, 1894. Serial No. 510,158- (No model.)

To aZZ whom it may concern:

Be it known that I, WILHELM BARHEINE, engineer, a subject of the King ofPrussia, Emperor of Germany, and a resident of 23 Diesdorferstrasse,Magdeburg, in the Kingdom of Prussia and Empire of Germany, haveinvented new and useful Improvements in Rod and Pipe Cutters, of whichthe following is aspecificaton, reference being had therein to theaccompanying drawings.

The subject-matter of this invention is a rod and pipe cutter, whichpermits a uniform cut of the metal in consequence of its peculiarconstruction.

In order that my invention may be better understood, I will now proceedto describe the same, reference being had to the accompanying drawingsand to the letters marked thereon.

Figure 1 is a side elevation of my improved rod and pipe cutter. Fig. 2is a plan bottom I view thereof. Fig. 3 is a longitudinal'section of theadjustable sleeve and-spring-sliding jaw on the line 00 as, Fig. 2. Fig.4 is an end View of the spring-sliding jaw. Fig. 5 is in part alongitudinal section and in part a side view of the brace holding a rod.Fig. 6 shows side views of the cutter.

A metal fixed jaw has a longitudinal slot a through its back, in whichis guided a sleeve 1) by means of a prismatic projection c. This sleeveslides within the jaw and lengthwise of the latter. In its front openingthe sleeve carries a sliding jaw d guided in the sleeve by screw-pins tin slots 1) and in the longitudinal slot aby a projection c and isperforated longitudinally by an opening 25 square in cross-section, inwhich is held a cutter 6, (shown in Fig. 6,) the cutting-faces of thecutter being of any desired shape. The sliding jaw is operated by ascrew f adj ustable in the fixed jaw, so as to force the cutter againstthe article to be out and is held to the sleeve by a cross-pin h seatedin its annular groove f .The jaw d is pressed out of the sleeve by avolnte spring Zlocated in the front opening of the sleeve, (see Fig. 3,)one end of which rests against the jaw and the other end of whichstrikes against a projection within the sleeve. The sliding jaw d hastwo curved recesses h. at its front end, in which are fitted twocircular disks in of a brace. Each of these disks is provided with aholein its center corresponding to the section of the article to be operatedupon. These holes are shown square in cross-section in Fig. 1. Thearticle to be operated upon is passed through these holes and thengripped in a vise or by any other suitable clamp. It now the device isrotated around the article, the disks k, occupying recesses of themovable jaw d, form a bearing for the latter, and the cutter (beingforced against the article by the operating-screwy) is carried aroundthe article as desired. The spring-pressure produces very even cutting.

In order to allow of the convenient handling of the cutter and toprovide a reliable coupling for the disks k, the latter are con--nected, as shown in Fig. 5, by abridge-block m, in which are providedscrew-pins n and 00. corresponding with the circular grooves r in thedisks. In order to prevent the turning over or canting of the piece tobeout off, the disk on that side of the cutter is provided with a sleeve 0and a clamp-screw 1).

Having thus described my invention, the following is what I claim as newtherein and desire to secure by Letters Patent:

1. A rod and pipe cutter comprising a fixed jaw, a sleeve slidinglongitudinally in ways of said fixed jaw, a sliding jaw, carried by thesleeve, a volute spring. located within the sleeve and bearing againstthe sliding jaw, a cutter mounted in the slidingjaw, and an operatingscrew coupled to the sleeve; substantially as described.

2. A rod and pipe cutter comprising a fixed jaw having a longitudinalslot, through its back, a vsliding sleeve, having a projection guided inthe slot, a sliding jaw, carried by the sleeve having a projectionguided in the slot pin and slot connections with the sleeve, and curvedrecesses at its end, a spring located within said sleeve, and bearingagainst the sliding jaw, a cutter mounted in the sliding jaw, a pair ofdisks for supporting the article operated upon and fitted to the curvedrecesses, and an operating screw connected with the sleeve;substantially as described.

3. A rod and pipe cutter comprising a fixed jaw, a sleeve sliding withinsaid fixed jaw, a

sliding jaw carried by the sleeve, having curved recesses, a cuttermounted in the sliding jaw, a spring located within the sleeve andbearing against the sliding jaw, a pair of disks for supporting thearticle to be oper ated upon, fitted to the curved recesses of thesliding jaw and an operating screw connected with the sleeve,substantially as described.

4. A rod and pipe cutter comprisingafixed jaw, a sleeve sliding withinsaid fixed jaw, a spring sliding jaw carried by the sleeve, hav ingcurved recesses, acutter mounted in the sliding jaw, a pair of diskshaving circular grooves and fitted to the curved recesses of the slidingjaw, and a brace consisting of a bridge-block and pins working throughthe Witnesses:
